General Description
The LM26420 regulator is a monolithic, high frequency, dual PWM step-down DC/DC converter in a 16 Pin LLP and a 20 Pin eTSSOP package.
It provides all the active functions to provide local DC/DC conversion with fast transient response and accurate regulation in the smallest possible PCB area.
Key Features
